IRAS and its Role in Taxation in Singapore

Overview of IRAS and its Role in Taxation in Singapore

What is IRAS

IRAS stands for Inland Revenue Authority of Singapore, which is the main tax administrator in Singapore. It is a statutory board under the Ministry of Finance, responsible for the administration and collection of taxes, as well as ensuring compliance with tax laws and regulations. The IRAS plays a vital role in the Singaporean taxation system, and Mercans can help businesses comply with its requirements.

The IRAS administers several types of taxes in Singapore, including income tax, goods and services tax (GST), property tax, stamp duty, betting taxes, and estate duty. The income tax is the largest source of revenue for the Singaporean government and is levied on individuals and companies based on their income. The GST, which is a consumption tax, is charged on the supply of goods and services in Singapore. The property tax is levied on the owner of the property based on its annual value, and the stamp duty is imposed on documents relating to property transactions.

Role of IRAS

The role of IRAS in Singapore’s taxation system is to ensure that taxes are collected efficiently and effectively, and that taxpayers comply with the tax laws and regulations. IRAS also provides guidance and support to taxpayers to help them understand their tax obligations and to promote voluntary compliance.

The IRAS has several initiatives in place to promote compliance, such as the Voluntary Disclosure Program, which encourages taxpayers to disclose any errors or omissions in their tax returns voluntarily. IRAS also conducts regular audits and investigations to ensure that taxpayers are complying with the tax laws.

In addition, the IRAS has implemented several e-services to make it easier for taxpayers to comply with their tax obligations. For example, taxpayers can file their tax returns and make payments online, and they can also access their tax accounts and receive e-notifications from IRAS.
